Current Information can be found at: Development of Computer-Aided Face-Fit Evaluation Methods - FY07


  • Establish up-to-date respirator fit-test panels and test headforms to be incorporated into the national and ISO standards
  • Develop an anthropometric database of Asian workers
  • Investigate the correlation between 3 -D parameters and face fit
Head and Face Anthropometric Survey of Respirator Users, 3D Head Form

Applicable Standards

  • ISO TC94 SC15 WG1 PG5
  • 29 CFR Part 1910.134

Key Partners

  • Anthrotech
  • WVU (Dennis Groce)
  • ISEA (provide fund for the study in Asia)


  • OSHA
  • MSHA
  • ANSI
  • ISO
  • Respirator Users and manufacturers

Project Scope

  • Develop an anthropometric survey detailing the face size distributions of respirator users using both traditional measurement methods and three-dimensional (3-D) scanning systems
  • Investigate the extent to which facial features can predict industrial respirator fit and protection
  • Develop respirator fit test panels using the traditional bivariate approach and the principal component analysis (PCA)
  • Develop test headforms


  • Develop respirator fit test panels
  • Determine correlation between 3-D parameters and fit
  • Develop test headforms


  • Manuscripts published in peer-reviewed journals (2 published, 3 in progress)
  • One paper was nominated for Shepard Best Scientific Paper Award by NIOSH
  • Presentations at scientific conferences (3 to be presented)


  • One ISO draft standard
  • Neck circumference data were incorporated into the CBRN standards
  • Some manufacturers started recruiting subjects for testing respirators
  • One new respirator model may have been certified (Aero)
